Pressure transmitters are indispensable key components in the fluid (gas, liquid) industry, pressure transmitters are mainly used in the following areas:
Petroleum/petrochemical/chemical industry:
With throttling devices, to provide accurate flow measurement and control. Can measure the pressure and liquid level of pipelines and storage tanks.
Electric power/city gas/other company undertakings:
Requires high stability and high precision measurement and other places.
Pulp and paper:
Used in places where chemical and corrosive resistant liquids are required.
Steel/non-ferrous metals/ceramics:
For furnace pressure measurement and other applications requiring high stability and accuracy. For stable measurement under strictly controlled conditions (temperature, humidity, etc.).
Machinery/Shipbuilding:
Used in places where stable measurement is required under tightly controlled (temperature, humidity, etc.) high-precision conditions.
There are many kinds of pressure sensors, the main ones are:1)Pressure sensors that utilize the piezoelectric effect of crystals2)Lee pressure sensors are the most commonly used kind of sensors in industrial practice, and the pressure sensors that we usually use are mainly manufactured by utilizing the piezoelectric effect, and such sensors are also called piezoelectric sensors. Piezoelectric sensors are mainly used in the measurement of acceleration, pressure and force. Piezoelectric acceleration sensors have been widely used in vibration and shock measurements in airplanes, automobiles, ships, bridges and buildings, especially in aviation and astronautics where they have a special place. Piezoelectric sensors can also be used to measure combustion pressure measurements and vacuum measurements inside engines. It can also be used in the military industry, for example, it is used to measure the instantaneous change in the chamber pressure of the gun bullet in the chamber and the muzzle of the shock wave pressure. It can be used to measure both large and small pressures. Piezoelectric sensors are also widely used in biomedical measurements
